This equation can also be expressed by replacing integration by summation over configurational states indicating jump process [1]}, [2]}, [3]} which is easier to handle and more directly related to physical systems [2]}. Master equation can also be seen as the time evolution of the configurational probability for Markov processes of systems that jump from one to another state which is due to birth and death processes of the particles in the system. There are different techniques to solve Master equation, namely, using generating function technique [5]}, Fourier transform technique [6]}, Laplace transform technique [7]}, Laplace-Fourier transform technique [8]} etc. However, solving Master equation of complex systems involving multi-variable is quite difficult except for simple systems.
